Effect of corrugated channel phase shifts on flow structures and heat transfer rate

Augmentation of Fluid Flow and Heat Transfer Characteristics in corrugated Channel: A Review Study

“…The effect of phase shift became more pronounced on heat transfer and fluid flow, especially at high Reynolds number values Tokgoz et al [1] 2018 Rectangular…”

“…The influence of the phase shift on the Nusselt number and overall performance factor was shown in Figure 26. The effect of three phase shifts (0 °, 90 °, and 180 °) of the rectangular corrugated channels on the thermal hydraulic performance characteristics under turbulent flow studied numerically by Tokgoz et al [1]. The study referred to the existence of significant effects on hydrodynamics and temperature distribution with the effect of aspect ratio and phase shift.…”

“…The mechanism of heat transfer enhancement in corrugated channels was based on several features available in corrugation geometry. The corrugation induces the eddies to emerge which enhances the flow mixing [1]. Besides, the corrugation prompts the boundary layer to be periodically interrupted and redeveloping which significantly enhances heat transfer [2].…”

Mixed Convection in a Lid‐Driven Cavity with Triangular Corrugations and Built‐in Triangular Block

“…The increase in the height of the corrugations resulted in the increased turbulence intensity along with the axial direction. Tokgoz et al [30] performed a combined experimental and numerical study on the hydrodynamic and thermal behavior in the channel containing corrugated walls for various phase shift angles and turbulent flow.…”
